Abstract
A surface mount type light-emitting unit includes a light-emitting device. A first lead is connected electrically to a first electrode of the light-emitting device. A second lead is connected electrically to a second electrodc of the light-emitting device. A clear insulator seals the light-emitting device, a section connecting the first electrode to the first lead and a section connecting the second electrode to the second lead. An end of the first lead, forming a reflecting section, is molded into a cup-shaped portion having a flat bottom. The light-emitting device is bonded to the flat bottom. A surface of the reflecting section opposed to the flat bottom is exposed to a surface of thc insulator.
